The results show that increase in demand for feedstock to produce bio-ethanol will lead to large increase in the prices of agricultural products. The increase in prices will trigger a significant rise in the production of feedstock at the cost of lower rice and wheat production. The study also reveals that the impacts of bio-ethanol on farmers" incomes vary largely among regions and farmer groups. Given the expected expansion of bio-ethanol production in the future, and the limited land resources for feedstock production in China, the viability of different crops as feedstock for bio-ethanol requires careful analysis before a large-scale expansion of China's bio-ethanol program. Bio-ethanol production in China should be relying more on the second generation of bio-ethanol technologies (i.e. using celluloses to produce bio-ethanol), and China's government should increase research investment in this field.展开更多

IntroductionThere have been numerous studies on free capital mobility, its management and impact on developing countries’ economy during the past decades. International capital flows create opportunities for portfolio diversification and risk sharing. In classical cases, capital mobility permits a more efficient global allocation of savings and directs resources toward their most productive uses (Fischer, 1998, etc.). However,展开更多

Chinas rapid economic expansion hasaffected the quality of its growth, with rising material and energy consumption and imbalancedeconomic structure as the main manifestations. Regarding macroeconomic policy options in2004, decision-makers should shift the policy focus from control of deflation to preventionof inflation; the pace of economic growth should be properly set; a balance betweenconsumption and investment should be strengthened by controlling excessive expansion ofinvestment, and industrial restructuring should be conducted in a coordinated manner onthe basis of properly controlling the overly rapid industrial growth; policies should becontinued to boost exports and sustainable growth of foreign investment; and more effortsshould be made to accelerate the change in the mode of economic growth.展开更多
